ABSTRACT

A method including determining, by a first device in communication with a second device in a mesh network, an instant message to be transmitted to the second device; and encrypting, by the first device, the instant message based at least in part on utilizing a symmetric key negotiated between the first device and the second device; and selectively transmitting, by the first device to the second device, the instant message over a meshnet connection between the first user device and the second user device in the mesh network. Various other aspects are contemplated.

FIELD OF DISCLOSURE

Aspects of the present disclosure generally relate to communications in networks, and more particularly to optimized messaging in a mesh network.

BACKGROUND

Users may rely on mesh networks (also referred to as “meshnets”) to communicate (e.g., transmit and/or receive) data among a plurality of endpoints (e.g., user devices) via one or more Internet nodes (e.g., bridges, switches, infrastructure devices, etc.). In an example, a mesh network may include a plurality of endpoints communicatively coupled to each other directly or via the one or more Internet nodes. A mesh network in which all endpoints are communicatively coupled to each other may be referred to as a fully connected network. Data transmitted by a first endpoint, from among the plurality of endpoints, may be routed over the Internet via the one or more Internet nodes to a second endpoint from among the plurality of endpoints. Also, data transmitted by the first endpoint may be routed to two or more endpoints from among the plurality of endpoints.

In a mesh network, the plurality of endpoints may cooperate with each other to enable communication of the data among the plurality of endpoints. In an example, one or more of the endpoints may participate in communication of the data. In this way, the mesh network may avoid relying on a given endpoint for communication of the data. Some mesh networks may have the ability to dynamically self-organize and self-configure the plurality of endpoints. This ability may allow such mesh networks to enable dynamic distribution of workloads, particularly in the event that one or more endpoints should fail. Further, installation overhead may be reduced.

SUMMARY

In one aspect, the present disclosure contemplates a method including determining, by a first device in communication with a second device in a mesh network, an instant message to be transmitted to the second device; encrypting, by the first device, the instant message based at least in part on utilizing a symmetric key negotiated between the first device and the second device; and selectively transmitting, by the first device to the second device, the instant message over a meshnet connection between the first user device and the second user device in the mesh network.

In another aspect, the present disclosure contemplates a first device including a memory and a processor configured to: determine, while in communication with a second device in a mesh network, an instant message to be transmitted to the second device; encrypt the instant message based at least in part on utilizing a symmetric key negotiated between the first device and the second device; and selectively transmit, to the second device, the encrypted instant message over a meshnet connection between the first device and the second device in the mesh network.

In another aspect, the present disclosure contemplates a non-transitory computer readable medium storing instructions, which when executed by a processor associated with a first device, cause the processor to: determine, while in communication with a second device in a mesh network, an instant message to be transmitted to the second device; encrypt the instant message based at least in part on utilizing a symmetric key negotiated between the first device and the second device; and selectively transmit, to the second device, the encrypted instant message over a meshnet connection between the first device and the second device in the mesh network.

FIG. 1 is an illustration of an example 100 associated with optimized messaging in a mesh network, according to various aspects of the present disclosure. Example 100 shows an architectural depiction of included components. In some aspects, the components may include one or more user devices 102 capable of communicating with a mesh network service provider (MSP) control infrastructure 104 for purposes of obtaining mesh network services. In some aspects, the one or more user devices 102 may communicate with the MSP control infrastructure 104 over a network 118. The MSP control infrastructure 104 may be controlled by a mesh network service provider and may include an application programming interface (API) 106, a user database 108, processing unit 110, and a meshnet database 112. In some aspects, a user device 102 may utilize a processing unit 116 and/or a client application 114, which is provided by the MSP control infrastructure 104, to communicate with the API 106. The API 106 may be capable of communicating with the user database 108 and with the processing unit 110. Additionally, the processing unit 110 may be capable of communicating with the meshnet database 112, which may be capable of storing data associated with providing mesh network services.

The user device 102 may be a physical computing device capable of hosting the client application 114 and of connecting to the network 118. The user device 102 may be, for example, a laptop, a mobile phone, a tablet computer, a desktop computer, a smart device, a router, or the like. In some aspects, the user device 102 may include, for example, Internet-of-Things (IoT) devices such as MSP smart home appliances, smart home security systems, autonomous vehicles, smart health monitors, smart factory equipment, wireless inventory trackers, biometric cyber security scanners, or the like. The network 118 may be any digital telecommunication network that permits several nodes to share and access resources. In some aspects, the network 118 may include one or more of, for example, a local-area network (LAN), a wide-area network (WAN), a campus-area network (CAN), a metropolitan-area network (MAN), a home-area network (HAN), Internet, Intranet, Extranet, and Internetwork.

The MSP control infrastructure 104 may include a combination of hardware and software components that enable provision of mesh network services to the user device 102. The MSP control infrastructure 104 may interface with (the client application on) the user device 102 via the API 106, which may include one or more endpoints to a defined request-response message system. In some aspects, the API 106 may be configured to receive, via the network 118, a connection request from the user device 102 to establish a connection with the MSP control infrastructure 104 for purposes of obtaining the mesh network services. The connection request may include an authentication request to authenticate the user device 102. The API 106 may receive the authentication request and a request for the mesh network services in a single connection request. In some aspects, the API 106 may receive the authentication request and the request for the mesh network services in separate connection requests.

The API 106 may further be configured to handle the connection request by mediating the authentication request. For instance, the API 106 may receive from the user device 102 credentials including, for example, a unique combination of a user ID and password for purposes of authenticating the user device 102. In another example, the credentials may include a unique validation code known to an authentic user. The API 106 may provide the received credentials to the user database 108 for verification.

The user database 108 may include a structured repository of valid credentials belonging to authentic users. In one example, the structured repository may include one or more tables containing valid unique combinations of user IDs and passwords belonging to authentic users. In another example, the structured repository may include one or more tables containing valid unique validation codes associated with authentic users. The mesh network service provider may add or delete such valid unique combinations of user IDs and passwords from the structured repository at any time. Based at least in part on receiving the credentials from the API 106, the user database 108 and a processor (e.g., the processing unit 110 or another local or remote processor) may verify the received credentials by matching the received credentials with the valid credentials stored in the structured repository. In some aspects, the user database 108 and the processor may authenticate the user device 102 when the received credentials match at least one of the valid credentials. In this case, the mesh network service provider may provide mesh network services to the user device 102. When the received credentials fail to match at least one of the valid credentials, the user database 108 and the processor may fail to authenticate the user device 102. In this case, the mesh network service provider may decline to provide mesh network services to the user device 102.

When the user device 102 is authenticated, the user device 102 may initiate a connection and may transmit to the API 106 a request for the mesh network services. The processing unit 110 included in the MSP control infrastructure 104 may be configured to determine a mesh network associated with the user device 102 and/or to identify one or more user devices to be included within the determined mesh network. The processing unit 110 may utilize the API 106 to transmit information associated with the mesh network and/or the identified one or more user devices to the user device 102. The user device 102 may transmit an initiation request to establish secure connections (e.g., encrypted tunnels) with the one or more user devices. In some aspects, the one or more user devices with which the user device 102 establishes the secure connections may also host respective client applications for communicating with the MSP control infrastructure 104 and/or with the user device 102. In some aspects, the processing unit 110 may be a logical unit including a logical component configured to perform complex operations associated with computing, for example, numerical weights related to various factors associated with providing the meshnet services.

One or more components (e.g., API 106, user database 108, processing unit 110, and/or meshnet database 112, processing unit 116) included in the MSP control infrastructure 104 and/or included in the user device 102 may further be associated with a controller/processor, a memory, a communication interface, or a combination thereof (e.g., FIG. 7 ). For instance, the one or more components of the set of components may include or may be included in a controller/processor, a memory, or a combination thereof. In some aspects, the one or more of the components included in the MSP control infrastructure 104 may be separate and distinct from each other. Alternatively, in some aspects, the one or more of the components included in the MSP control infrastructure 104 may be combined with one or more of the other components. In some aspects, the one or more of the components included in the MSP control infrastructure 104 and/or the user device 102 may be local with respect to each other. Alternatively, in some aspects, one or more of the components included in the MSP control infrastructure 104 and/or the user device 102 may be located remotely with respect to one or more of other components included in the MSP control infrastructure 104 and/or the user device 102. Additionally, or alternatively, one or more components of the components included in the MSP control infrastructure 104 and/or the user device 102 may be implemented at least in part as software stored in a memory. For example, a component (or a portion of a component) may be implemented as instructions or code stored in a non-transitory computer-readable medium and executable by a controller or a processor to perform the functions or operations of the component. Additionally, or alternatively, a set of (one or more) components shown in FIG. 1 may be configured to perform one or more functions described as being performed by another set of components shown in FIG. 1 .

As indicated above, FIG. 1 is provided as an example. Other examples may differ from what is described with regard to FIG. 1 .

Endpoints (e.g., user devices) may rely on a mesh network to communicate (e.g., transmit and/or receive) meshnet data among the endpoints. In example 200 shown in FIG. 2 , the endpoints may include a first user device, a second user device, a third user device, and/or a fourth user device. The meshnet data may be communicated using wired communications and/or wireless communications over a network such as, for example, the Internet. The meshnet data may include any information including digital information such as, for example, documents including data, voice data, image data, signal data, and/or video data. Further, the mesh network may be a secure mesh network that may enable the endpoints to communicate the meshnet data in encrypted form via meshnet connections (shown as double-ended arrows in FIG. 2 ).

In some cases, the user devices in the mesh network may communicate via instant messages. To communicate via instant messages, a transmitting user device and a receiving user device may download and utilize respective dedicated instant messaging (IM) applications made available by an instant messaging service provider. In an example, the first user device may utilize a first IM application to communicate an instant message to a second IM application utilized by the second user device. Such instant message may not be communicated via the meshnet connection between the first user device and the second user device and may not be considered meshnet data.

The instant message may be communicated over the open Internet (e.g., clearnet). As a result, the instant message may not be encrypted and any private information included in the instant message may be traced, identified, and/or collected by a malicious third party. Privacy of the first user device and/or the second user device may be compromised, and the user devices may be unable to, among other things, privately communicate instant messages.

Also, the instant message may be routed from the first IM application to a central server operated by the instant messaging service provider before being routed to the second IM application. The instant messaging service provider may fail to protect the communicated information included in the instant message. In an example, a third party may gain unauthorized access to the communicated information by, for example, hacking into the central server. In another example, internal devices associated with the instant messaging service provider that have access to the servers may gain unauthorized access to the communicated information. As a result, an integrity associated with the communicated information may be compromised. To restore the integrity, the user devices and/or the instant messaging service provider may expend resources (e.g., management resources, memory resources, computational/processing resources, power consumption resources, system bandwidth, network resources, etc.) that may otherwise be utilized to perform more suitable tasks.

Further, routing the instant message via the central server, as opposed to communicating the instant message directly between the first user device and the second user device, may consume user device resources (e.g., processing resources, memory resources, power consumption resources, battery life, or the like) and network resources (computational resources, network bandwidth, management resources, processing resources, memory resources, or the like) that may otherwise be utilized to perform more suitable tasks. The above discussion with respect to the first user device and the second user device may also apply to the one or more other user devices in the mesh network.

Various aspects of systems and techniques discussed in the present disclosure enable optimized messaging in a mesh network. In some aspects, an MSP control infrastructure may provide the mesh network to enable endpoints to securely communicate meshnet data. Further, the MSP control infrastructure may provide the endpoints with respective client applications to communicate with the MSP control infrastructure, to communicate with each other for setting up respective meshnet connections to be utilized for communicating meshnet data in the mesh network, and/or to communicate the meshnet data (e.g., meshnet communications) with each other over the respective meshnet connections. The MSP control infrastructure and the respective client applications may also enable optimized messaging in the mesh network. In some aspects, the respective client applications may enable the endpoints to communicate (e.g., transmit and/or receive) instant messages as meshnet data, in encrypted form via respective meshnet connections. In some aspects, the respective client applications may include graphical user interfaces to receive information via local input interfaces to transmit instant messages and/or to display information included in received instant messages. The respective client application may encrypt/decrypt the instant messages based at least in part on utilizing respective symmetric keys negotiated among the endpoints. The respective client applications may enable a transmitting endpoint to select one or more receiving endpoints based at least in part on an identification associated with the one or more receiving endpoints. The respective client applications may enable a transmitting endpoint to select the one or more receiving endpoints based at least in part on a registered account with which the one or more receiving endpoints is associated. In this way, the MSP infrastructure and/or the respective applications may enable optimized messaging in the mesh network without the endpoints installing additional dedicated IM applications, communicating unencrypted instant messages, or communicating with a central server external to the mesh network. Further, the MSP infrastructure and/or the respective applications may enable communication of instant messages in encrypted form via existing meshnet connections. As a result, privacy and/or integrity of information included in the instant messages is protected, and user device resources (e.g., processing resources, memory resources, power consumption resources, battery life, or the like) and network resources (computational resources, network bandwidth, management resources, processing resources, memory resources, or the like) may be utilized to perform more suitable tasks associated with the mesh network.

In some aspects, a processor (e.g., processing unit 116, processor 720) associated with a user device may determine, while in communication with a second device in a mesh network, an instant message to be transmitted to the second device; encrypt the instant message based at least in part on utilizing a symmetric key negotiated between the first device and the second device; and selectively transmit, to the second device, the encrypted instant message over a meshnet connection between the first device and the second device in the mesh network.

As indicated above, FIG. 2 is provided as an example. Other examples may differ from what is described with regard to FIG. 2 .

FIG. 3 is an illustration of an example flow 300 associated with optimized messaging in a mesh network, according to various aspects of the present disclosure. The example flow 300 may include a first user device (e.g., first endpoint), MSP control infrastructure 104, and a second user device (e.g., second endpoint) in communication with each other. The first user device and the second user device may be similar to a user device 102 discussed above with respect to FIG. 1 . In some aspects, the first user device and the second user device may be associated with a single account registered with the MSP control infrastructure 104. In some aspects, the first user device and the second user device may be associated with different accounts registered with the MSP control infrastructure 104. In some aspects, the first user device and the second user device may be located locally (e.g., in the same room, in the same building, etc.). In some aspects, the first user device and the second user device may be located remotely (e.g., in different buildings, in different cities, in different states, in different countries, etc.) with respect to each other.

The first user device may install a first client application (e.g., client application 104) and the second user device may install a second client application (e.g., client application 104), the first client application and the second client application being associated with (e.g., provided by) the MSP control infrastructure 104. The first user device and the second user device may use the respective client applications to communicate with an application programming interface (API) and/or a processor (e.g., processing unit 110, processor 720) associated with the MSP control infrastructure 104. In some aspects, the first user device, the MSP control infrastructure 104, and the second user device may communicate with each other over a network (e.g., network 118). As discussed herein, the MSP control infrastructure 104 may enable the first user device and/or the second user device to obtain the mesh network services and/or communicate via instant messages.

In some aspects, the client applications may enable the user devices to receive information to be processed by the client applications and/or by the MSP control infrastructure 104. Each of the client applications may include respective graphical user interfaces to receive the information via local input interfaces (e.g., touch screen, keyboard, mouse, pointer, etc.) associated with the user devices. The information may be received via text input or via a selection from among a plurality of options (e.g., pull down menu, etc.). In some aspects, the first client application and/or the second client application may activate and/or enable the graphical interface for receiving the information and/or displaying received information. For instance, the first client application (or the second client application) may cause a screen (e.g., local screen) associated with the first user device (or the second user device) to display, for example, a pop-up message to request entry of the information. The client applications may enable communication of at least a portion of the information to the MSP control infrastructure 104. The client applications may enable communication of information among the user devices. In some aspects, the first client application may utilize a first processing unit (e.g., processing unit 116, processor 720) associated with the first user device to perform processes/operations associated with optimized messaging in the mesh network and the second application may utilize a second processing unit (e.g., processing unit 116, processor 720) associated with the second user device to perform processes/operations associated with optimized messaging in the mesh network.

Although only two user devices (e.g., endpoints) are shown in FIG. 3 , the present disclosure contemplates the mesh network to include any number of user devices that perform the processes discussed herein in a similar and/or analogous manner. For instance, the mesh network may include a third user device and a fourth user device, as discussed above with respect to FIG. 2 , that perform the processes discussed herein in a similar and/or analogous manner. User devices may leave or join the mesh network in an ad-hoc manner.

As shown by reference numeral 305, the first user device may register an account with the MSP control infrastructure 104. In some aspects, during the registration, the first user device may provide registration information such as, for example, identity of an owner of the first user device, a phone number associated with the first user device, an email address associated with the first user device, or the like. In some aspects, the first user device may set up an access system including login information (e.g., access information) such as, for example, username, password, or the like to subsequently gain access to the registered account. In some aspects, the first user device may share the login information with other user devices (e.g., second user device) associated with the first user device to enable the other user devices to utilize the login information to gain access to the MSP control infrastructure 104 via the registered account. In some aspects, a given user device may be associated with the first user device because the given user device may be available to a user/owner of the first user device. In some aspects, when the second user device is not associated with the registered account associated with the first user device, the second user device may register a different account with the MSP control infrastructure 104.

In some aspects, the first user device and the second user device may utilize the login information to access the registered account/accounts to communicate with the MSP control infrastructure 104. As shown by reference numeral 310, based at least in part on the first user device and the second user device accessing the registered account/accounts to communicate with the MSP control infrastructure 104, the MSP control infrastructure 104 may transmit, and the first client application and the second client application may receive, MSP access information. In some aspects, the MSP access information may include UDP access information. The UDP access information may include information regarding an infrastructure UDP IP address and an infrastructure UDP port associated with the MSP control infrastructure 104. The MSP control infrastructure 104 may utilize the infrastructure UDP IP address and the infrastructure UDP port to communicate utilizing the UDP. In some aspects, the first user device and the second user device may utilize the infrastructure UDP IP address and the infrastructure UDP port to communicate with the MSP control infrastructure 104 regarding the mesh network. Further, the first client application and the second client application may obtain from, for example, a domain name services (DNS) server, transmission control protocol (TCP) access information associated with the MSP control infrastructure 104. Such TCP access information may include information regarding an infrastructure TCP IP address and an infrastructure TCP port associated with the MSP control infrastructure 104. The MSP control infrastructure 104 may utilize the infrastructure TCP IP address and the infrastructure TCP port to communicate utilizing the TCP.

As shown by reference numeral 315, the first client application and the second client application may determine information based at least in part on the registration of the account/accounts with the MSP Control Infrastructure 104. In an example, the first client application may determine an asymmetric first assigned key pair associated with the first user device. The first assigned key pair may be unique to the first user device and may include a first assigned public key and a first assigned private key. In this way, the first assigned public key and the first assigned private key may be device-specific and maybe associated with the registered account. In some aspects, the first assigned public key and the first assigned private key may be associated with each other via, for example, a mathematical function. As a result, data encrypted using the first assigned public key may be decrypted by utilizing the first assigned private key.

Similarly, the second client application may determine an asymmetric second assigned key pair associated with the second user device. The second assigned key pair may be unique to the second user device and may include a second assigned public key and a second assigned private key. In this way, the second assigned public key and the second assigned private key may be device-specific and maybe associated with the registered account. In some aspects, the second assigned public key and the second assigned private key may be associated with each other via, for example, a mathematical function. As a result, data encrypted using the second assigned public key may be decrypted by utilizing the second assigned private key.

As shown by reference numeral 320, the client applications may transmit, and the MSP control infrastructure 104 may receive, at least a portion of the information determined by the client applications. For instance, the first client application may transmit, for example, the first assigned public key to the MSP control infrastructure 104 and the second client application may transmit, for example, the second assigned public key to the MSP control infrastructure 104. The MSP control infrastructure 104 may store and correlate the received information in association with the registered account and/or with the respective user devices. In an example, the MSP control infrastructure 104 may store and correlate the first assigned public key in association with the registered account and the first user device, and may store and correlate the second assigned public key in association with the registered account and the second user device. In some aspects, the first client application and the second client application may utilize the infrastructure UDP IP address or the infrastructure TCP IP address and the infrastructure UDP port or the infrastructure TCP port to transmit the first assigned public key and the second assigned public key to the MSP control infrastructure 104 via the TCP.

Further, as shown by reference numeral 325, the MSP control infrastructure 104 may determine that the first user device and the second user device are to be included in the same mesh network. In some aspects, when the first user device and the second user device are associated with the same registered account, the MSP control infrastructure 104 may make such a determination regarding the secure mesh network based at least in part on determining that the first user device and the second user device are communicating with the MSP control infrastructure 104 by utilizing the login information associated with the same registered account. In some aspects, when the first user device and the second user device are associated with different registered accounts, the MSP control infrastructure 104 may make such a determination regarding the secure mesh network based at least in part on the first user device (and/or the second user device) providing information indicating that the first user device and the second user device are to be included in the same mesh network. Such information may include, for example, identification information (e.g., type of device, user name, email address, etc.) associated with the second user device (or the first user device), the second IP address (or the first IP address), or the like.

Based at least in part on determining that the first user device and the second user device are to be included in the same mesh network, as shown by reference numeral 330, the MSP control infrastructure 104 may determine meshnet IP addresses for the first user device and for the second user device. In an example, the MSP control infrastructure 104 may determine a first meshnet IP address associated with the first user device and a second meshnet IP address associated with the second user device. The first client application and/or another application installed on the first user device and/or the operating system associated with the first user device may utilize the first meshnet IP address and/or the first local meshnet port to communicate data with the endpoints over meshnet connections in the mesh network and the second client application and/or another application installed on the second user device and/or the operating system associated with the second user device may utilize the second meshnet IP address and/or the second local meshnet port to communicate data with the endpoints over the meshnet connections in the mesh network. In an example, with respect to communication between the first user device and the second user device, the first user device may determine a first meshnet IP packet indicating the first meshnet IP address as a source address, the first local meshnet port as a source port, the second meshnet IP address as a destination address, and the second local meshnet port as a destination port. The first user device may encrypt and encapsulate the first meshnet IP packet within a payload of a transmitted UDP IP packet. The second user device may receive the UDP IP packet, may decrypt the first meshnet IP packet, and may route the first meshnet IP packet to the second local meshnet port. Similarly, the second user device may determine a second meshnet IP packet indicating the second meshnet IP address as a source address, the second local meshnet port as a source port, the first meshnet IP address as a destination address, and the first local meshnet port as a destination port. The second user device may encrypt and encapsulate the second meshnet IP packet within a payload of a transmitted UDP IP packet. The first user device may receive the UDP IP packet, may decrypt the second meshnet IP packet, and may route the second meshnet IP packet to the first local meshnet port. The MSP control infrastructure 104 may determine the first meshnet IP address and the second meshnet IP address from, for example, a pool of reserved IP addresses included in a subnet associated with an internal network of the ISP.

As shown by reference numeral 335, the first user device and the second user device may transmit, and the MSP control infrastructure 104 may receive, respective binding requests. In some aspects, the first user device may transmit the first binding request to the MSP control infrastructure 104 using the UDP by utilizing the UDP access information received from the MSP control infrastructure 104 (e.g., block 320). In this case, the first user device may transmit a first binding request to the MSP control infrastructure 104 to request the MSP control infrastructure 104 to determine a first public UDP IP address (e.g., communication address) and/or a first public UDP port (e.g., communication port) associated with the first user device. As discussed below in further detail, the first public UDP IP address and/or the first public UDP port are to be utilized by the second user device to communicate with the first user device in the mesh network. Similarly, the second user device may transmit the second binding request to the MSP control infrastructure 104 using the UDP by utilizing the UDP access information received from the MSP control infrastructure 104 (e.g., block 320). In this case, the second user device may transmit a second binding request to the MSP control infrastructure 104 to request the MSP control infrastructure 104 to determine a second public UDP IP address (e.g., communication address) and/or a second public UDP port (e.g., communication port) associated with the second user device. As discussed below in further detail, the second UDP IP address and/or the second UDP port are to be utilized by the first user device to communicate with the second user device in the mesh network.

In some aspects, the first public UDP IP address and/or the first public UDP port may be determined by a first NAT device (e.g., a router) responsible for managing operation of the first user device in a first local network. In an example, the first NAT device may translate a first local UDP IP address and/or a first local UDP port associated with the first user device to the first public UDP IP address and/or the first public UDP port that the first user device utilizes to communicate (e.g., transmit and/or receive) over the Internet using the UDP. Similarly, the second public UDP IP address and/or the second public UDP port may be determined by a second NAT device responsible for managing operation of the second user device in a second local network. In an example, the second NAT device may translate a second local UDP IP address and/or a second local UDP port associated with the second user device to the second public UDP IP address and/or the second public UDP port that the second user device utilized to communicate (e.g., transmit and/or receive) over the Internet using the UDP.

Based at least in part on receiving the respective binding requests, as shown by reference numeral 340, the MSP control infrastructure 104 may determine public UDP IP addresses and/or public UDP ports associated with the first user device and the second user device. In an example, based at least in part on receiving the first binding request, the MSP control infrastructure 104 may determine the first public UDP IP address and/or the first public UDP port associated with the first user device. In some aspects, the MSP control infrastructure 104 may determine the first public UDP IP address and/or the first public UDP port based at least in part on analyzing the UDP communication (e.g., UDP IP packet) including the first binding request received from the first user device. The UDP communication may include, for example, a header that indicates the first public UDP IP address as a source UDP IP address and/or the first public UDP port as a source UDP port associated with the first user device. Further, the MSP control infrastructure 104 may store and correlate the first public UDP IP address and/or the first UDP port in association with the first user device in, for example, the meshnet database 112. Similarly, based at least in part on receiving the second binding request, the MSP control infrastructure 104 may determine the second public UDP IP address and/or the second public UDP port associated with the second user device. In some aspects, the MSP control infrastructure 104 may determine the second public UDP IP address and/or the second public UDP port based at least in part on analyzing the UDP communication (e.g., UDP IP packet) including the second binding request received from the second user device. The UDP communication may include, for example, a header that indicates the second public UDP IP address as a source UDP IP address and/or the second public UDP port as a source UDP port associated with the second user device. Further, the MSP control infrastructure 104 may store and correlate the second public UDP IP address and/or the second public UDP port in association with the second user device in, for example, the meshnet database 112.

Based at least in part on determining the public UDP IP addresses and/or the public UDP ports, as shown by reference numeral 345, the MSP control infrastructure 104 may transmit, and the first client application and the second client application may receive, communication information. In an example, the MSP control infrastructure 104 may transmit, and the first client application may receive, first communication information including the first meshnet IP address associated with the first user device, the second meshnet IP address associated with the second user device, the second public UDP IP address and/or the second public UDP port associated with the second user device, and the second public key associated with the second user device. Similarly, the MSP control infrastructure 104 may transmit, and the second client application may receive, second communication information including the first public UDP IP address and/or the first public UDP port associated with the first user device, the first public key associated with the first user device, the first meshnet IP address associated with the first user device, and the second meshnet IP address associated with the second user device. As discussed below in further detail, the above transmission of communication information may enable the first user device and the second user device to communicate securely and privately in the mesh network.

In some aspects, the MSP control infrastructure 104 may determine account information associated with the user devices included in the mesh network. In an example, when the mesh network includes the first user device, the second user device, the third user device, and the fourth user device, as discussed above with respect to example 200 of FIG. 2 , the MSP control infrastructure 104 may determine a correlation between a given user device and a registered account associated with the given user device. For instance, with respect to example 200 of FIG. 2 , the MSP control infrastructure 104 may determine account information indicating, for example, that the first user device is associated with a first registered account, that the second user device is associated with a second registered account, and that the third user device and the fourth user device are both associated with a third registered account. The MSP control infrastructure 104 may transmit the determined account information to the user devices included in the mesh network via communication information. In an example, the MSP control infrastructure 104 may include the determined account information in the first communication information transmitted to the first user device, in the second communication information transmitted to the second user device, in the third communication information transmitted to the third user device, and/or in the fourth communication information transmitted to the fourth user device. In some aspects, one or more user devices included in the mesh network may be associated with a predetermined grouping (e.g., chat rooms, break out rooms, etc.) of devices. In this case, the account information may include information indicating an association of the one or more user devices with a grouping of devices. Further, the MSP control infrastructure 104 may update the account information and transmit updated communication information to the user devices based at least in part on determining a change in an association of the user device with a registered account and/or a change in an association of a user device with a grouping of devices.

As shown by reference numeral 350, the first client application and the second client application may communicate with each other directly to set up a meshnet connection (e.g., an encrypted tunnel) for communicating encrypted data in the hybrid mesh network. To set up the meshnet connection, the first client application may utilize the second assigned public key and/or the second public IP address (e.g., second UDP IP address) to securely (e.g., in encrypted form) communicate with the second client application, and the second client application may utilize the first assigned public key and/or the first public IP address (e.g., first UDP IP address) to securely communicate with the first client application. In some aspects, the first client application and the second client application may communicate to securely/privately negotiate parameters (e.g., a symmetric encryption/decryption key) associated with the meshnet connection. In some aspects, the parameters may be randomly generated to provide optimized security to the communications. In an example, the first client application and the second client application may privately negotiate a randomly generated symmetric key that is to be utilized by the first client application and the second client application for encrypting and decrypting data communicated via the meshnet connection. The randomly generated symmetric key may be determined based at least in part on any combination of the first public key, the second public key, and/or randomly generated numbers. Additionally, the first client application and the second client application may utilize a secure protocol (e.g., Wireguard, IP sec, etc.) to communicate the data via the meshnet connection.

Additionally, or alternatively, the first client application and the second client application may communicate with each other indirectly via, for example, a relay device (e.g., a relay server) to set up the meshnet connection. In an example, the first client application may provide the first assigned public key to a relay server, which may store an association of the first assigned public key with the first client application. In some aspects, the association may include an association between the first assigned public key and a first communication connection between the relay server and the first client application. Similarly, the second client application may provide the second assigned public key to the relay server, which may store an association of the second assigned public key with the second client application. In some aspects, the association may include an association between the second assigned public key and a second communication connection between the relay server and the first client application. The relay server may rely on the stored associations of public keys and client applications to determine a destination of a received message. In some aspects, the relay server may include a network of relay servers that enable the first client application and the second client application to communicate with each other. In this case, the first client application and the second client application may provide the respective assigned public keys to different relay servers included within the network of relay servers.

In some aspects, the first client application may transmit, to the relay server, a first message that is to be delivered to the second client application. Along with the first message, the first client application may transmit the second assigned public key. Further, the first client application may encrypt the first message utilizing the second assigned public key. In some aspects, the first client application may encrypt the first message based at least in part on utilizing the negotiated randomly generated symmetric key. Based at least in part on receiving the encrypted first message and the second assigned public key, the relay server may determine from stored associations that the second assigned public key is associated with the second client application. As a result, the relay server may determine that the first message is to be relayed (e.g., transmitted) to the second client application. Similarly, the second client application may transmit, to the relay server, a second message that is to be delivered to the first client application. Along with the second message, the second client application may transmit the first assigned public key. Further, the second client application may encrypt the second message utilizing the first assigned public key. In some aspects, the second client application may encrypt the second message based at least in part on utilizing the negotiated randomly generated symmetric key. Based at least in part on receiving the encrypted second message and the first assigned public key, the relay server may determine from stored associations that the first assigned public key is associated with the first client application. As a result, the relay server may determine that the second message is to be relayed (e.g., transmitted) to the first client application. In this way, the relay server may enable the first client application and the second client application to communicate with each other to set up the meshnet connection.

Based at least in part on setting up the meshnet connection, the first client application and the second client application may begin communicating encrypted data via the meshnet connection based at least in part on utilizing the negotiated parameters and the secure protocol. In a similar and/or analogous manner, the first client application may set up meshnet connections with a third client application installed in the third client application and with a fourth client application associated with the fourth client application. Also, in a similar and/or analogous manner, the second client application may set up meshnet connections with the first client application, the third client application, and the fourth client application. Further, in a similar and/or analogous manner, the third client application may set up meshnet connections with the first client application, the second client application, and the fourth client application. Finally, in a similar and/or analogous manner, the fourth client application may set up meshnet connections with the first client application, the second client application, and the third client application. Additional client applications that enter the mesh network may also set up meshnet connections with the other client applications included in the mesh network.

Further, based at least in part on setting up the meshnet connection, as shown by reference numeral 355, the user devices included in the mesh network may enable optimized messaging in the mesh network. In some aspects, the user devices may utilize respective client applications to enable optimized messaging in the mesh network by enabling the user devices to communicate (e.g., transmit and/or receive) instant messages as meshnet data, in encrypted form via respective meshnet connections.

With respect to the first user device, when the first client application and/or another application installed on the first user device determines IM information that is to be transmitted to a user device in the mesh network via an instant message, the first client application may determine the instant message. In an example, the first client application may activate a first graphical user interface associated with the first client application to receive the IM information. In some aspects, the first client application may receive the IM information via local input interfaces (e.g., touch screen, keyboard, mouse, pointer, etc.) associated with the first user device. Such IM information may include text information, multimedia (e.g., audio and/or video) information, files, documents, pictures, etc.

Based at least in part on determining the IM information, the first client application may cause a screen associated with the first user device to display a list of destination entries (e.g., destinations, the group of destinations, etc.) to whom the instant message may be transmitted. The first client application may populate the list based at least in part on account information received in the first communication information from the MSP control infrastructure 104 (e.g., block 345).

In the case of example 200 of FIG. 2 , the destination entries may include, for example, individual user devices including the second user device, the third user device, and the fourth user device. The first client application may enable selection of one or more individual user devices as destinations to whom the instant message is to be transmitted. In this case, the first client application may encrypt the instant message based at least in part on utilizing the symmetric key negotiated between the first user device and the selected user device, and may transmit the encrypted instant message to the selected user device over the meshnet connection between the first user device and the selected user device. In an example, when the second user device and the fourth user device are selected, the first client application may encrypt the instant message based at least in part on utilizing the symmetric key negotiated between the first user device and the second user device, and may transmit the encrypted instant message to the second user device over the meshnet connection between the first user device and the second user device. Similarly, the first client application may encrypt the instant message based at least in part on utilizing the symmetric key negotiated between the first user device and the fourth user device, and may transmit the encrypted instant message to the fourth user device over the meshnet connection between the first user device and the fourth user device. In some aspects, the first client application may substantially simultaneously transmit the encrypted instant message to the second user device and the encrypted instant message to the fourth user device

In some aspects, the destination entries may include registered accounts associated with the user devices such as a second registered account associated with the second user device and a third registered account associated with the third user device and the fourth user device. The first client application may enable selection of one or more registered accounts as destinations to whom the instant message is to be transmitted. In this case, the first client application may transmit the instant message to each user device associated with the selected registered account. In an example, when the third registered account is selected, the first client application may determine, based at least in part on the account information, that the third registered account is associated with the third user device and the fourth user device. As a result, the first client application may encrypt the instant message based at least in part on utilizing the symmetric key negotiated between the first user device and the third user device, and may transmit the encrypted instant message to the third user device over the meshnet connection between the first user device and the third user device. Similarly, the first client application may encrypt the instant message based at least in part on utilizing the symmetric key negotiated between the first user device and the fourth user device, and may transmit the encrypted instant message to the fourth user device over the meshnet connection between the first user device and the fourth user device. In some aspects, the first client application may substantially simultaneously transmit the encrypted instant message to the third user device and the encrypted instant message to the fourth user device.

In some aspects, the destination entries may include an entry (e.g., All Meshnet Devices) that enables the first client application to broadcast (e.g., transmit) the instant message to all user devices included in the mesh network. When this entry is selected, the first client application may substantially simultaneously transmit respective instant messages to each user device currently included in the mesh network. For instance, the first client application may respectively encrypt the instant message based at least in part on utilizing the symmetric key negotiated between the first user device and each other user device, and may transmit the encrypted instant message to each other user device over the respective meshnet connection between the first user device and each other user device. In an example, the first client application may encrypt the instant message based at least in part on utilizing the symmetric key negotiated between the first user device and the second user device, and may transmit the encrypted instant message to the second user device over the meshnet connection between the first user device and the second user device. Similarly, the first client application may encrypt the instant message based at least in part on utilizing the symmetric key negotiated between the first user device and the third user device, and may transmit the encrypted instant message to the third user device over the meshnet connection between the first user device and the third user device. Similarly, the first client application may encrypt the instant message based at least in part on utilizing the symmetric key negotiated between the first user device and the fourth user device, and may transmit the encrypted instant message to the fourth user device over the meshnet connection between the first user device and the fourth user device. In some aspects, the first client application may substantially simultaneously transmit the encrypted instant message to the second user device, the encrypted instant message to the third user device, and the encrypted instant message to the fourth user device.

In some aspects, the entries may include an entry (e.g., All Meshnet Accounts) that enables the first client application to broadcast (e.g., transmit) the instant message to user devices associated with all registered accounts. When this entry is selected, the first client application may substantially simultaneously transmit respective instant messages to each user device associated with a registered account currently included in the mesh network. For instance, the first client application may determine, based at least in part on the account information, that the second registered account is associated with the second user device. As a result, the first client application may encrypt the instant message based at least in part on utilizing the symmetric key negotiated between the first user device and the second user device, and may transmit the encrypted instant message to the second user device over the meshnet connection between the first user device and the second user device. Further, the first client application may determine, based at least in part on the account information, that the third registered account is associated with the third user device and the fourth user device. As a result, the first client application may encrypt the instant message based at least in part on utilizing the symmetric key negotiated between the first user device and the third user device, and may transmit the encrypted instant message to the third user device over the meshnet connection between the first user device and the third user device. Similarly, the first client application may encrypt the instant message based at least in part on utilizing the symmetric key negotiated between the first user device and the fourth user device, and may transmit the encrypted instant message to the fourth user device over the meshnet connection between the first user device and the fourth user device. In some aspects, the first client application may substantially simultaneously transmit the encrypted instant message to the second user device, the encrypted instant message to the third user device, and the encrypted instant message to the fourth user device.

In some aspects, the destination entries may include group entries (e.g., Chatroom1, Chatroom2, Breakroom1, Breakroom 2, etc.) that enable the first client application to broadcast (e.g., transmit) the instant message to a group of user devices included in the mesh network. When this entry is selected, the first client application may substantially simultaneously transmit respective instant messages to each user device associated with a selected group in the mesh network. For instance, Chatroom1/Breakroom1 may be associated with the second user device and the third user device, Chatroom2/Breakroom2 may be associated with the third user device and the fourth user device, and so on. When the Chatroom1/Breakroom1 entry is selected, the first client application may determine, based at least in part on the grouping of user devices, that Chatroom1/Breakroom1 is associated with and/or includes the second user device and the third user device. As a result, the first client application may encrypt the instant message based at least in part on utilizing the symmetric key negotiated between the first user device and the second user device, and may transmit the encrypted instant message to the second user device over the meshnet connection between the first user device and the second user device. Also, the first client application may encrypt the instant message based at least in part on utilizing the symmetric key negotiated between the first user device and the third user device, and may transmit the encrypted instant message to the third user device over the meshnet connection between the first user device and the third user device. In some aspects, the first client application may substantially simultaneously transmit the encrypted instant message to the second user device and the encrypted instant message to the third user device.

Similarly, when the Chatroom2/Breakroom2 entry is selected, the first client application may determine, based at least in part on the grouping of user devices, that Chatroom2/Breakroom2 is associated with and/or includes the third user device and the fourth user device. As a result, the first client application may encrypt the instant message based at least in part on utilizing the symmetric key negotiated between the first user device and the third user device, and may transmit the encrypted instant message to the third user device over the meshnet connection between the first user device and the third user device. Also, the first client application may encrypt the instant message based at least in part on utilizing the symmetric key negotiated between the first user device and the fourth user device, and may transmit the encrypted instant message to the fourth user device over the meshnet connection between the first user device and the fourth user device. In some aspects, the first client application may substantially simultaneously transmit the encrypted instant message to the third user device and the encrypted instant message to the fourth user device.

In some aspects, the above encryption of the instant message based at least in part on utilizing the negotiated symmetric key may include a first encryption of the instant message. In some aspects, after the first encryption of the instant message based at least in part on utilizing the negotiated symmetric key, the first user device may again encrypt (e.g., second encryption) the first encrypted instant message. In some aspects, the first encryption may take place at an application layer included in a network stack associated with performing communication operations associated with the first user device, and the second encryption may take place at a lower layer (e.g., presentation layer, session layer, network layer, transport layer, etc.) as compared to the application layer in the network stack.

The second encryption may include encrypting the first encrypted instant message based at least in part on utilizing a public key associated with a destination user device. For instance, when the first client application determines that the instant message is to be transmitted to the second user device, the first client application may first encrypt the instant message based at least in part on utilizing the negotiated key between the first user device and the second user device, as discussed herein. Further, the first user device may second encrypt the first encrypted instant message based at least in part on utilizing the second public key associated with the second user device. The first user device may then transmit the second encrypted instant message to the second user device over the meshnet connection between the first user device and the second user device. Similarly, when the first client application determines that the instant message is to be transmitted to the third user device, the first client application may first encrypt the instant message based at least in part on utilizing the negotiated key between the first user device and the third user device, as discussed herein. Further, the first user device may second encrypt the first encrypted instant message based at least in part on utilizing a third public key associated with the third user device. The first user device may then transmit the second encrypted instant message to the third user device over the meshnet connection between the first user device and the third user device. Similarly, when the first client application determines that the instant message is to be transmitted to the fourth user device, the first client application may first encrypt the instant message based at least in part on utilizing the negotiated key between the first user device and the fourth user device, as discussed herein. Further, the first user device may second encrypt the first encrypted instant message based at least in part on utilizing a fourth public key associated with the fourth user device. The first user device may then transmit the second encrypted instant message to the fourth user device over the meshnet connection between the first user device and the fourth user device.

In some aspects, the first user device may suspend transmission of the instant message when a selected user device (may also be referred to as a destination user device and/or receiving user device) is not currently included (e.g., temporarily disconnected) in the mesh network. In this case, the first user device may suspend the first encryption and/or the second encryption and/or transmission of the instant message. In some aspects, the first user device may determine that the selected user device is not currently included in the mesh network based at least in part on determining that the meshnet connection between the first user device and the selected user device is currently disconnected. Further, the first user device may automatically resume the first encryption and/or the second encryption and/or transmission of the instant message based at least in part on determining that the selected user device is currently included (e.g., reconnected) in the mesh network. In some aspects, the first user device may determine that the selected user device is currently included in the mesh network based at least in part on determining that the meshnet connection between the first user device and the selected user device is currently connected or reconnected.

In some aspects, the other user devices (e.g., second user device, third user device, fourth user device, etc.) included in the mesh network may operate to optimize the messaging in a similar and/or analogous manner as discussed herein with respect to the first user device. For instance, the other user devices in the mesh network may, among other things, determine IM information, may determine and display a list of destination entries based at least in part on account information, enable selection of a destination user device and/or registered account and/or predetermined grouping, etc., may first encrypt and/or second encrypt the instant message, and may transmit the instant message as meshnet data, in encrypted form via respective meshnet connections, as discussed herein. Additional user devices that enter the mesh network may also optimize the messaging, as discussed herein.

In this way, the MSP infrastructure and/or the respective applications may enable optimized messaging in the mesh network without the user devices installing additional dedicated IM applications or communicating with a central server external to the mesh network. Further, the MSP infrastructure and/or the respective applications may enable communication of instant messages in encrypted form via existing meshnet connections. As a result, privacy and/or integrity of information included in the instant messages is protected, and user device resources (e.g., processing resources, memory resources, power consumption resources, battery life, or the like) and network resources (computational resources, network bandwidth, management resources, processing resources, memory resources, or the like) may be utilized to perform more suitable tasks associated with the mesh network.

FIG. 5 is an illustration of an example process 500 associated with optimized messaging in a mesh network, according to various aspects of the present disclosure. In some aspects, the process 500 may be performed by a memory and/or a processor/controller (e.g., processing unit 116, processor 720) associated with a user device/endpoint (e.g., user device 102) running a client application. As shown by reference numeral 510, process 500 may include determining, by a first device in communication with a second device and a third device in a mesh network, a first instant message to be transmitted to the second device and a second instant message to be transmitted to the third device, the first instant message and the second instant message including instant messaging (IM) information. For instance, the user device (e.g., second user device) may utilize a communication interface (e.g., communication interface 770) with the associated memory and/or processor to determine, while in communication with a second device and a third device in a mesh network, a first instant message to be transmitted to the second device and a second instant message to be transmitted to the third device, the first instant message and the second instant message including instant messaging (IM) information, as discussed elsewhere herein.
